Is everything OK , Madam ?   Well , I'm trying to buy some foreign currency for my holiday .   I can help you with that . Holiday , you say ? Lucky you ! Where are you going to be travelling to ?   We are going to Macau to visit my niece . She said it's better for me to bring US dollars , is that right ?   That is one option , Madam . If your are travelling to either Hong Kong or Macau we are permitted to exchange up to 1,000 USD for you .   OK , I see . What's the exchange rate ? Is the dollar up or down ?   Today's rate is 823 . 71 RIB to 100 USD .   To be honest , I have no idea about these things ! But I'm sure that's alright .   Yes , it's not bad . I will need to see your passport though .
